巴音布鲁克亚高山草原生态系统有机碳贮量的估算

通过实地调查,结合前人的研究资料,利用GIS技术通过MapInfo软件完成对遥感影像的解译获得草地类型数据的基础上,首次对巴音布鲁克亚高山草原生态系统的有机碳贮量进行了估算结果表明,巴音布鲁克亚高山草原生态系统地上植物体碳总量约为7.198×104t,其中地上部分约为3.199×104t,约占44.44;;地下部分根系约为3.999×104t,约占55.56;.巴音布鲁克亚高山草原生态系统土壤有机碳的平均碳通量为16.801 C kg/m2,土壤有机碳总贮藏量约为3 019.224×104t.

Estimation of Organic Carbon Storage of Bayinbuluke Alpine Grassland Ecosystem

Combining field survey with research data from predecessor,and based on the grassland type data obtained from interpretation of remote sensing images through MapInfo software with GIS technique,organic carbon storage of Bayinbuluke alpine grassland ecosystem was estimated.The statistical analysis demonstrates that gross carbon of above-ground vegetation of Bayinbuluke alpine grassland ecosystem is about 7.198×10~4 tons,of which the above-ground part is about 3.199×10~4 tons,which amounts to 44.44%;while underground root system around 3.999×10~4 tons,which covers about 55.56%.Average carbon flux of soil organic carbon of Bayinbuluke alpine grassland ecosystem is 16.801 C kg/m~2,and the total storage of soil organic carbon is about 3 019.244×10~4 tons.
